Q: Code P0172 came up in my 2010 Chevy Malibu. The dealer charged me $100 to troubleshoot the code. I was told that all the sensors were good and to run the gas tank low and fill up with high-octane gas. Does going to high-octane gas make any sense to you? The “Check engine” light is still on and I’m concerned that if another code comes up I’ll never know. What do you think?
